Http redirector


Hello Guys,

I have a android device that are being used as a "android router / tethering / wifi sharing" by many android devices.

Is it possible to create an app to run in my android wifi sharing device so that it will intercept all http request of all android devices connected to it and have it redirected to a default web page?

Example: If Android User A connects the device in my android WIFI / tethering sharing, each time user a opens his browser it will always go to a particular default page.

Thank you guys, hope you could give me some idea or direct to a resources.
